As was mentioned, you will need to calibrate your HDMI connection. Also, try setting the 622 to send 1080i through the HDMI. I know your tv is 720p but it will rescale the signal instead of the 622. See what you think.ok 8 bit I kinda got you now.
The 622 is set to 720p. As well the tv is 720p 42 inch plasma.
Watching HD channels. It just seems that when I made the switch the picture became slightly lighter and not quite as crisp.
